Description
Technical field
The present invention relates to wireless communication technology field, in particular to a kind of method and apparatus of network auto-adapt.
Background technique
Currently, as (the 4th Generation mobile communication technology, forth generation move 4G
The dynamic communication technology) etc. in network system based on data service, can not be wireless to be promoted by adjusting the coverage area of network
The effect of network resource scheduling, but improve the effect of wireless network resource scheduling by resource scheduling algorithm, it is common to provide
Source dispatching algorithm mainly includes that polling dispatching, max carrier to interference scheduling and Proportional Fair dispatch scheduling algorithm, specific as follows:
Polling dispatching algorithm, user uses the shared resource of network in turn, without considering instantaneous channel conditions.
Max carrier to interference scheduling algorithm is that a kind of typical utilization " multi-user diversity effect " Lai Shixian system performance group is big
The scheme of change only follows the principle of best performance in scheduling process, and system resource is fully allocated to the optimal user of performance,
To obtain the maximization of network performance.
Proportional Fair dispatches institute's method, it is contemplated that the compromise of throughput of system and fairness, when handling capacity is network units
The quantity of interior successful data transmission is measured with units such as bit, byte, groupings, and network system is by the algorithm to small
Each user distributes a corresponding priority in area, and the maximum user of priority receives network service in cell, and user's is excellent
First grade at least can take into account two factors of handling capacity and fairness, is guaranteeing throughput of system preferably simultaneously, is promoting length as far as possible
The priority for the user that phase cannot service guarantees opposite justice.
But for currently used resource scheduling algorithm, there are the following problems:
For polling dispatching algorithm, all communication links are provided by polling dispatching algorithm due to network system
Service quality is identical, therefore just needs to distribute more radio resources for the communication link of poor channel, further, since poll
Scheduling does not consider instantaneous channel conditions in scheduling process, therefore it will lead to lower overall system performance, though it is carried with maximum
It is dry to be compared than scheduling, there is more balanced service quality between each communication link, but do not improve wireless network money really
The effect of source scheduling.
For max carrier to interference scheduling algorithm, the maximization of system performance is only pursued, and is ignored completely for public affairs
The considerations of levelling, when the wireless environment locating for the intra-cell users is poor, it will cause to cannot get network service for a long time.Therefore from
From the point of view of user service angle, the fairness of the program is worst.
For Proportional Fair dispatching algorithm, although it is contemplated that the compromise of throughput of system and fairness.But in routine
Proportional Fair scheme in, mainly consider two factors of locating wireless environment and accumulative handling capacity of user, but influence net
The factor of network performance is numerous, as the factors such as transmission power, QoS (Quality-of-Service, quality of service) requirement are not added
Consider, it will it is not relatively optimal for leading to final scheduling result.
In conclusion the effect of wireless network resource scheduling at present is poor.
